“…Few data are available for Papiliotrema , formerly Cryptococcus . Members of this genus were found to be predominant in rice‐storage granaries (Shi et al., 2021) while, in soil, Papiliotrema laurentii was observed to develop a synergic interaction with AMF to improve plants' uptake of N and P (Leguina et al., 2019) and the solubilization of scarcely soluble forms of phosphate (apatites) and zinc (ZnO and ZnCO 3 ) (Kumla et al., 2020). The presence of Papiliotrema in the charcoal kiln soils of Macate can be attributed to the possible presence of phosphatic minerals, which could have been generated by repeated combustions in the same area; the higher availability of P in this soil supports this hypothesis.…”

This study provides a metataxonomic analysis of the fungal communities in soils under slash‐and‐burn agroforestry system and offers new insights into the relationships between fungal populations and soil physicochemical features such as pH, the particle size distribution, easily oxidizable organic carbon, total nitrogen, available phosphorus, and the mineralogical composition. Soils from three locations in central Mozambique—Vanduzi, Sussundenga, and Macate—that are subjected to slash‐and‐burn were considered to assess the effects of the forest fallow length (temporal variation) and of the land use (charcoal kiln, crop field, and forest; meaning horizontal variation) on the fungal community. The fungi of the genetic horizons (vertical variation) were also considered. Most of the detected fungi were decomposers, antagonists of plant pathogens, and plant‐growth promoters; they were differently distributed in relation to the soil's physicochemical properties and the soil use. The variations in the fungi distribution among the locations and between the horizons were considerable, while there were few variations between the different land‐use types. The limited differences between land uses indicate the inability of a forest fallow period shorter than 50 years to improve soil fertility and induce changes in the fungal community. The pedological approach used to identify and sample soil horizons allowed us to clearly distinguish the fungal community of the A horizons, those richest in organics and nutrients, and that of the Bo horizons, which have poor fertility.

“…Papiliotrema laurentii (reclassified from Cryptococcus laurentii) is a yeast that commonly inhabits soils and surfaces of plants (rhizospheric and epiphytic microorganism) , and can hydrolyze polyester coatings and coating components. − A Papiliotrema laurentii environmental isolate from an aircraft was recently shown to fractionally degrade a polyester-polyether polyurethane (PEST-PEUR) coating through preferential ester hydrolysis and utilize polyester metabolites as carbon sources . In this work, we focus on further understanding initial PEST-PEUR deterioration mechanisms by P.…”

Edge-Localized Biodeterioration and Secondary Microplastic Formation by Papiliotrema laurentii Unsaturated Biofilm Cells on Polyurethane Films

et al. 2020

Painted environmental surfaces are prone to microbiological colonization with potential coating deterioration induced by the microorganisms. Accurate mechanistic models of these interactions require an understanding of the heterogeneity in which the deterioration processes proceed. Here, unsaturated biofilms (i.e., at air/solid interfaces) of the yeast Papiliotrema laurentii were prepared on polyether polyurethane (PEUR) and polyester-polyether polyurethane (PEST-PEUR) coatings and incubated for up to 33 days at controlled temperature and humidity with no additional nutrients. Transmission micro-Fourier transform infrared microscopy (μFTIR) confirmed preferential hydrolysis of the ester component by the biofilm. Atomic force microscopy combined with infrared nanospectroscopy (AFM-IR) was used to analyze initial PEST-PEUR coating deterioration processes at the single-cell level, including underlying surfaces that became exposed following cell translocation. The results revealed distinct deterioration features that remained localized within ∼10 μm or less of the edges of individual cells and cell clusters. These features comprised depressions of up to ∼300 nm with locally reduced ester/urethane ratios. They are consistent with a formation process initiated by enzymatic ester hydrolysis followed by erosion from water condensation cycles. Further observations included particle accumulation in the broader biofilm vicinity. AFM-IR spectroscopy indicated these to be secondary microplastics consisting of urethane-rich oligomeric aggregates. Overall, multiple contributing factors have been identified that can facilitate differential deterioration rates across the PEST-PEUR surface. Effects of the imposed nutrient conditions on Papiliotrema laurentii physiology were also apparent, with cells developing the characteristics of starvation response, despite the availability of polyester metabolites as a carbon source. The combined results provide new laboratory insights into field-relevant microbiological polymer deterioration mechanisms and biofilm physiology at polymer coating interfaces.

“…The yeasts could face challenges in nature due to the change of single or combination of changes of multiple factors . As P. laurentii has a global distribution, especially in soils associated with plants, so there may be every chance that the yeast could encounter stress in the environment generated due to nitrogen deprivation as well as because of the presence of lead, arsenic, and chromium . So, P. laurentii could act like a model organism as the results could have implications on how these yeasts survive in the natural environment.…”

Removal of Pb (II), As (III), and Cr (VI) by nitrogen‐starved Papiliotrema laurentii strain RY1

Heavy metals such as lead, chromium, and metalloid like arsenic dominate the pinnacle in posing a threat to life. Being environment‐friendly, elucidating the mechanism by which microorganisms detoxify such elements has always been an active field of research hitherto. In the present study, we have investigated the capability of nitrogen‐deprived Papiliotrema laurentii strain RY1 toward enhanced tolerance and neutralizing toxic elements. There were biosorption and bioprecipitation of lead and chromium at the cell surfaces. Bioprecipitation mechanisms included the formation of lead phosphates and pyromorphites from lead, grimaldite from chromium. Transcripts such as metallothionein, aquaporins, and arsenical pump‐driving ATPase have been surmised to be involved in the detoxification of elements. Furthermore, activation of antioxidant defense mechanisms for the cells for each of the elements should contribute towards yeast's propagation. The efficiency of removal of elements for live cells and immobilized cells were high for lead and chromium. To the best of our knowledge, this is the first report of such high tolerance of lead, arsenic, and chromium for any yeast. The yeast showed such varied response under dual stress due to nitrogen starvation and in the presence of respective elements. The yeast possesses promising potentials in nitrogen deprived and enriched environments to aid in bioremediation sectors.
